check if above capacity, ( two threads can pass )
they collect all keys, sort, then cut down to the size thats needed ( both threads will have a similar list )
the keys in the list are removed to make room ( which will be many of the same keys )
new upload is added ( only enough room was made for each upload on its own bcz the lists were similar )
then cache is over capacity
? maybe lock during next out idk
